10. System panel connector (10-1 pin PANEL1)
This connector accommodates several system front panel functions.
• System Power LED Lead (2-pin PWR LED)
This 2-1 pin connector connects to the system power LED. The LED lights up
when you turn on the system power, and blinks when the system is in sleep
mode.
• Hard disk activity LED (2-pin HD LED)
This 2-pin connector supplies power to the hard disk activity LED. The read
and write activities of any device connected to the primary or secondary IDE

This connector connects a switch that controls the system power. Pressing the
power switch turns the system between ON and SLEEP, or ON and SOFT
OFF, depending on the BIOS or OS settings. Pressing the power switch while
in the ON mode for more than 4 seconds turns the system OFF.
• Reset Switch Lead (2-pin RESET)
This 2-pin connector connects to the case-mounted reset switch for rebooting
the system without turning off the system power.
